Plasma Vitamin C

Manuscript Figure

Patient plasma vitamin C level. A) Composition of all patients, placebo controls, and vitamin C treated individuals with: vitamin C deficiency, inadequate vitamin C, or adequate vitamin C at inclusion; distributions are relatively similar between the two treatment arms. B) Plasma vitamin C level at each timepoint by treatment arm; p-values were estimated using robust linear mixed-effects model with a random intercept for each individual. C) LOESS smoothed vitamin C level over time with standard error ribbons. Individuals with >200 /L vitamin C level were censored in C) to better characterize dispersion among trial participants, all individual measures are shown in panel B).

Cox model (No interaction)

Supplemntal figure XX. Forest plot for adjusted Cox model. Cox proportional hazards regression to estimated efficacy of vitamin C on overall survival was adjusted for patient age at inclusion, gender, hemoglobin levels at inclusion, and whether or not they had been diagnosed with CCUS.

Cox model (Age interaction)

Supplemental figure XX. Forest plot for adjusted Cox model in age interaction. Cox proportional hazards regression to estimated efficacy of vitamin C as a function of age. Age was mean centered and converted to decades to improve hazard ratio scales. Overall vitamin C was still effective, with evidence that it’s efficacy decreases with age.

2-year landmark

Maybe Figure? A 2 year landmark analysis was performed to determine if there was still evidence of vitamin C efficacy after removing individuals who had events prior to 2 years. This landmark analysis ensures the effects of vitamin C had sufficient time to reach efficacy.

Competing risk regression (progression)

For this analysis death is a competing risk of high-risk progression. We are a bit limited in sample size and events; there are only 14 progression events. Power to detect any differences in progression is quite low and we will have difficulty adjusting for any covariates here. We see corroboration with our overall survival findings that death (the dotted lines) are significantly different, however we do not have enough evidence to determine if progression also differs.

Global Methylation

Figure XX. Global methylation changes over time by treatment arm A) 5-mC/dG and B) 5-hmC/5-mC level for each patient at inclusion and end-of-therapy (EOT) and the change in these measures between inclusion and EOT. Data were analyzed using robust linear mixed-effects models with a random intercept for each patient and an interaction between treatment and time point to assess if measures changed differently over time. Models also included a covariate for batch.

Cytokine figure

Supplemental Figure XX. log2 fold-change in cytokine measures that changed significantly. Data were analyzed using robust linear mixed-effects models with a random intercept for each patient and an interaction between treatment and timepoint to assess if measures changed differently over time. Larger points indicate the mean log2(fold-change) with 95% CI error bars. Scales were limited to +/-1.5 log2(fold-change) to better characterize dispersion, all data points are shown in supplemental figure XX. P-values were false discovery rate adjusted using Benjamini-Hochberg.
